But it seems that Pacquaio reasoning changed after ugas became Spence substitute opponent, because it was clear that pacquaio wanted to reclaim the belt that was revoked by the world boxing federation and give it to ugas for free at the time , i think in that match pacquaio was too eager to beat ugas with a knockout defeat and it drains he stamina . we all know the current pacquaio is not the pacquaio of three years ago who is able to move fast and aggressively, I think his legs are starting to weaken and slow down because of the age factor.
